EDUARD FRIESDORF, OF BIETIGHEIM, GERMANY.

STEAM AND OIL SEPARATOR.

SPECIFICATION forming part of Letters Patent No. 704,022, dated July 8, 1902. Application filed November 18, 1901. Serial No. 82,770. (No model.)

To all whom t may concern:

Beit known that I, EDUARD FRIEsDoRF, engineer, residing at Bietigheim, in the Kingdom of Wrtemberg and Empire of Germany,

have invented certain new and useful Improvements in Steam and'Oil Separatore, (for which I have filed an application for patent in Germany, bearing date April 22,` 1901,) of which the following is a speciiication.

In my improved apparatus the desired object is attained by the exhaust-steam coming from the engine and passing through the device, being subjected to a division or distribution of its volume, each half of this volume I5 before being again united to the other half being compelled to traverse a-zigzag path over vertically-arranged plates or ribs, which remove from the passing steam the molecules of oil, as well as the condensed water, and con- 2o duct the same to a lower collecting-space rectangularly located to the steam-inlet, from which this mixture of oil and water thus collected is conducted away by means of tubes to a special vessel and the oil and water after 5 separated.

In the accompanying drawings, Figure 1 is a vertical section; Fig. 2, a plan of theapparatus comprising my invention.

The apparatus consists in general of a box 3o or oute'r vessel b of rectangular section, open at the top and provided with a double'bottom. Upon the upper half of its two vertical narrow sides horizontal nozzles are provided, one of which, the nozzle c,serving for the inlet and 3 5 the nozzle CZ for the outlet or Vdischarge of the steam. The broad sides of the box are provided on their interior surfaces with a number of vertical ribs Z, arranged at certain distances from each otherat an angle of about 4o forty-five degrees toward their bearing edges or surfaces, the front edges or surfaces of the ribs being inclined in the direction of the steam-inlet. The box b is provided with a ilat cover a, having on the inner side a longitudinal wall g, extending to the bottom of the said face, the front edges or surfaces being, however, inclined in the direction of the outlet d.

These latter ribs h are so located that they project into the intermediate spaces between the ribs Z of the outer vessel. The upper bottom of the vessel bis provided with a row of perforations or openings corresponding to the number of ribs upon the outer vessel and the lid-ribs. An outlet d is also located in one of the narrow sides of the space between the two bottoms. The steam entering the apparatus through the nozzle c becomes, as will be apparent, distributed to both sides of the vertical longitudinal dividing-wall g and passes or iiows in a zigzag direction to the outlet-nozzle d. Along this path the steam, as will also be clear, strikes against the various surfaces of the ribsh and Z, as also against the dividingwall g, as well as against the inner walls of the vessel b,whereby the oil and condensationwater carried With the steam is caused to be deposited and iowing down from these sur faces through the holes i into the space f between the two bottoms of the outer vessel pass together through the opening e into a special collecting vessel, as hereinbefore described.

What I claim, and desire to secure by Letters Patent of the United States, is-

In an apparatus for the separation of oil and condensation-water from exhaust-steam, the combination of a rectangular outer vessel open at the top and provided with a double bottom, verticalribs arranged on the inner side of the two longitudinal Walls of same,said ribs beinginclined toward their bearing edges or surfaces,horizontal nozzles for the inlet and outlet of the steam ,located on the two narrow sides of the outer vessel, a flat cover having on its inner side a central wall extending to the bottom of the said outer vessel when the parts are assembled, the said middle Wall being provided with a number of Vertical ribs inclined toward their bearing surfaces or edges, and projecting between said vertical ribs of the-side Walls, as and for the purpose set forth.

In witness whereof I have hereunto signed my name this 4th day of November, 1901, in the presence of two subscribing witnesses.

EDUARD FRIESDORF.
